The specific embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figures 1 to 4, the scrapper conveyor of the present embodiment has housing 11, in housing 11, be provided with and be oppositely arranged to obtain the first sprocket wheel 12 and the second sprocket wheel, the first sprocket wheel 12 is arranged on the first end of housing 11 rotationally, and the second sprocket wheel is arranged on the second end of housing 11 rotationally.In housing 11, be also provided with flight chain, flight chain comprises and is set in the messenger chain on the first sprocket wheel 12 and the second sprocket wheel and is connected to a plurality of scraper plates on messenger chain.The scrapper conveyor of the present embodiment is also provided with the first curved baffle 21 in housing 11, this first curved baffle 21 is positioned at the first sprocket wheel 12 away from a side of the second sprocket wheel, and has the first feed back space coordinating with scraper plate between the first curved baffle 21 and the first sprocket wheel 12.The scrapper conveyor of the present embodiment, by arranging of the first curved baffle 21 reduced material in the housing 11 can stackeding space, thereby can make the moving material that is scattered in the first sprocket wheel 12 sides of scraper flight can turn back on transportation route and discharge housing, avoid material in prior art cannot again be transmitted the problem that chain is transported to discharging opening after the first sprocket wheel side is piled up, avoided material in the serious problem of the interior accumulation of housing 11, and then reduce the operation burden of stacking material to scrapper conveyor, and then reduce the spontaneous combustion probability of stacking material.
The first curved baffle 21 is fixed in housing 11, preferably by connecting element, is connected with housing 11.In housing 11, be also provided with the first track plates 31 and the second track plates 33, the first track plates 31 and the second track plates 33 and be all arranged between the first sprocket wheel 12 and the second sprocket wheel, and the second track plates 33 is positioned at the below of the first track plates 31., there is the reverse-running section of messenger chain the transportation section that has messenger chain in the first track plates 31 upper supports in the second track plates 33 upper supports.As shown in Figure 1, at the roof middle part of housing 11, offer inlet point, at the diapire middle part of housing 11, offer discharging opening, and on the second track plates 33, the position of reply discharging opening is had to breach.When scrapper conveyor starts, the first sprocket wheel 12 rotates and the second sprocket rotation, thereby band is automatically connected in the first sprocket wheel 12 to be connected and to carry out circulating motion with scraper plate on the second sprocket wheel, when material is from inlet point enters, the scraper plate that can be connected the transmission section on messenger chain drives and together moves with this section of scraper plate, until material is while moving to the indentation, there of the second track plates 33 with the reverse-running section on messenger chain, material can drop from indentation, there, and leaves housing 11 from discharging opening.
Scrapper conveyor in the present embodiment also comprises drive motor, on the output shaft of drive motor, be connected with rotating shaft 15, preferably, the first sprocket wheel 12 is two, the parallel setting of two the first sprocket wheels 12 and rotating shaft 15 wore two the first sprocket wheels 12, and drive motor is to drive the first sprocket wheels 12 to rotate by rotating shaft 15 in work, and then make the first sprocket wheel 12 drive flight chain and the motion of the second sprocket wheel, complete the task that drive motor drives remaining part work.Arrow in Fig. 3 shows the rotation direction of the first sprocket wheel 12, and as can be seen from the figure, move along the direction of the first sprocket wheel 12 to second sprocket wheels in the transportation section of flight chain.
As shown in Figures 2 and 3, at the first track plates 31, near one end of the first sprocket wheel 12, be also provided with the plate 32 that connects material, the plate 32 that connects material is obliquely installed and towards the first sprocket wheel 12, extends downwards.First plate 32 that connects material is preferably convex, and the first protuberance that connects material plate 32 is positioned at the one end away from the first track plates 31.Preferably, this protuberance extend between two the first sprocket wheels 12.Further preferably, the distance between protuberance and rotating shaft 15 is between 30mm to 50mm.In increase, connect material after plate 32, the material that is brought to the first sprocket wheel 12 sides can be fallen and connect material on plate 32, and flight chain can drive and drop on the material connecting material on plate 32 and move, and finally makes this part material discharge at discharging opening place, is transported to downstream.The setting of plate 32 connects material, guaranteed that material can drop into and connect material on plate 32 the cyclic process from the first sprocket wheel 12 sides, prevented that the situation of overflow from appearring in solid accumulation and the phenomenon and the material that kill messenger chain in the first sprocket wheel 12 sides, simultaneously, also can reduce the wearing and tearing of power consumption and messenger chain, prevent the damage of bearing.
As shown in Figure 4, the second end in housing 11 is movably provided with strut bar 16, and strut bar 16 is positioned at the second sprocket wheel away from a side of the first sprocket wheel 12.On strut bar 16, be provided with rotationally tail wheel, and on tail wheel with tightening device, so that messenger chain is carried out to regular tensioning according to the wear pattern of messenger chain.On strut bar 16, be also connected with fixed support, on fixed support, be connected with the second curved baffle 22, and between the second curved baffle 22 and the second sprocket wheel, there is the second feed back space coordinating with scraper plate.Because the second curved baffle 22 is connected on strut bar 16 by fixed support, can together move with strut bar 16, guaranteed that the distance between the second curved baffle 22 and scraper plate remains unchanged.
The second curved baffle 22 is identical with the effect of the first curved baffle 21, be all reduced material in housing 11 can stackeding space.Preferably, the first curved baffle 21 and and scraper plate between distance be 50mm, the distance between the second curved baffle 22 and scraper plate is 50mm.Such distance setting, can guarantee that material is less than 50mm at the ulking thickness at first end place and the second end place, avoid can material at the bulk deposition at first end place and the second end place, prevent the spontaneous combustion of material.
In the above-described embodiments, scrapper conveyor strut bar 16 when work does not occur then tail wheel rotates, if the tail wheel of scrapper conveyor is rotational structure, the second curved baffle 22 can be fixed by fastener with the slide plate that is positioned at the second sprocket wheel side, when also can realize the second curved baffle 22 with tail wheel, move, reach preventing materials accumulation effect.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
